ment as to admit of loose sheets or leaves being readily-bound in properor desirable relation with ach other in such manner as to permit theready removal of one or more of said sheets or leaves, or the insertionof additional or substitute sheets or leaves; to so construct myimproved binder as to render the saline convenient tor use. heat inappearance and inexpensive in construction and to produce certainotherimprovements, the details of construction and operation of which will bemore fully pointed out herein after. These objects I accomplish in themanner illustrated in the accompanying drawingin which: I

1 represents the usual upper and lower cover boards of a book which aretlexiblv connected with the longer edges of a central curved back piece2 which may be of the usual or any well known form, this curved backpiece being omitted for the sake of clearnoss in illustration in Fig. 2of the drawing. -l'n producing the binding members of my device, Iemploy two parallel mctal back plates 3, each of which is slightlycurved in crosssection as shown, the ad joining edges of said platesbeing formed at intervals with tubular projections such as are indicatedath and 5, the projections of one of said members 3 being adapted, asshown, to enter the spaces between the cor- Application filed February 2Specification of Letters Patent.

responding projections of the other niem ber, thereby forming acontinuous hinge tube through which passes a hinge rod 6'.

As shown more clearly at T in Fig. 3'91: the drawing, the upper andlower or outer marginal portions ot the plates 3 are bent for 'ardly.said bent portions being doubled upon themselves and shaped in theirouter portions to form barrels or tubes i These tubes T are notched orcut-a ayv at desirable intervals as indicated at T. the notches of oneof the tubes 7* being opposite or in transverse alinementwith thenotches of the remaining tube T. '8 and 9 represent respectively rodswhich are adapted to be removably inserted into the tubes T and 7.

Each of the plate members 3 has hingedthereto at the roar of its flangeprojection I, as shown at 79. a plate 10 which is adapted to have itsouter portion suitably secured to or in the rear end portion of thecover board 1. By thus coni'iecting the wings or plate members 10 withthe rear ends of the cover boards. it will be observed that the:

' curved back in the metallic binder, which is composed of the sections3, will be retained in the position shown within the curved back member2 of the book cover.

T he paper sheets or leaves 11 which are to be bound by the bindingappliance herein shown, are formed at their inner ends with two or moreopenings 11 which openings when said sheets are laid one upon the other,are adapted to register one with the other. In binding these leaves, Iemploy two or more metallic binding bars 12 which are p'refe ably curvedrearwardly, as shown, and

which are provided in their upper and lower portions with suitablyseparated openings 12*. These bars are adapted to be inserted throughthe registeringopenings1.1 of the sheets 11,, the ends of the barsfitting into the notches 7" of the tube 7* in the manner indicated more.clearly in Fig. 3 of the drawing. This being accomplished the bindingbars 12- are removably secured in place by inserting the locking rods 8and 9 through the tube members 7 and through corresponding holes 12 ofthe bars 12.

In the modified form of the device shown in Fig. 2, the parts aresubstantially like thos above described except, that; a plate 10 is usedin place of the plate 10 shown in Figs. 1 and 3, the object. ofconstructing the plate asshown in this figure being to space the coverfrom the ends of the bars 12 to' was?! Assuming that it is desired toremove some of the sheets in the upper half of the' book, it willbe'understood that bypulling the upperrod 8 outward from engagement withthe upper'ends of the bars 12 and permitting the upper cover board andupper curved plate member 3' to drop downward to the position indicatedin dotted lines in Fig. 2 of the drawing thejdesired number of leaves magagement Witlithebindingbars 12, or new leaves may be readily added tothose already bound together. It is also'evident that by removing boththe rods 8 and 9, all the bound leaves may be-readilyv disengaged fromthe bars 12-, or if desired-the bound body of leaves together with thebinding bars may be removed from engagement with the binder back. Byproviding more than-one opening 12 in the member-12,-- it will be seenthat the thickness of -the device as a whole may be reduced when only afew leaves are carried upon said members When said leaves are so few innumber that they do not cover the inner openings '12, the hinge rods 8and 9 are inserted through these inner openings, the hinged connectionor" the members 3 permitting this to be done.

From the construction and operation described, it will be seenthatcomparatively simple and inexpensive means are rovided for readily andconveniently binding loose leaves into book form and for disconnectingor removing said leaves from the What I claim, is: Y
